Anion-Driven Self-Assembly Processes Based on Halogen-Bonding

摘要

This report results from a contract tasking Polytechnic of Milan as follows: From a supramolecular point of view anionic species play a key role in many mineral or biological processes. Since XB has been rationalized as a charge transfer interaction with a strong electrostatic character, the higher the electron density on the donor site, the stronger the resulting interaction. The increase of electron density on the anions was pursued by using inorganic salts (ISs), as source of co-ordinating anions. The complexed anions are thus expected to become nucleophilic enough to give rise to strong XBs able to drive the self-assembly of PFCs, HOs, and ISs.
